What is the output of this formula selecting a range?

In Google Sheets, what will be the result of entering the formula =SUM(B2:D2) if the cells B2, C2, and D2 contain the values 5, 10, and 15 respectively?

Google Sheets

=SUM(B2:D2)

A 10

B 15

C 30

D 5

💡 Hint

Think about what the SUM function does with a range of cells.

The formula sums all values in cells B2, C2, and D2. Since they are 5, 10, and 15, the total is 30.

❓ Function Choice

Which formula selects the entire third row?

You want to select all cells in the third row of a Google Sheet to sum their values. Which formula correctly selects the entire third row?

A =SUM(3:3)

B =SUM(C3:C)

C =SUM(A3:Z3)

D =SUM(3:C)

💡 Hint

Selecting a whole row uses the row number before and after the colon.

Using 3:3 selects the entire third row. Other options either select a column or are invalid.

What is the output of this mixed cell selection formula?

Given the following values in Google Sheets:
- A1 = 2
- B1 = 3
- C1 = 4
What is the result of the formula =SUM(A1, B1:C1)?

Google Sheets

=SUM(A1, B1:C1)

A Error

B 7

C 5

D 9

💡 Hint

SUM can take single cells and ranges together.

The formula sums A1 (2) plus the range B1:C1 (3 + 4), total 2 + 3 + 4 = 9.

🎯 Scenario

Selecting columns with dynamic ranges

You have a Google Sheet where column A has names and columns B to E have monthly sales data. You want a formula that sums all sales for the first person in row 2, but the number of months (columns) can change. Which formula correctly sums all sales from column B to the last column with data in row 2?

A =SUM(B2:OFFSET(B2,0,COUNTA(2:2)-1))

B =SUM(B2:INDEX(2:2, COUNTA(2:2)))

C =SUM(B2:E2)

D =SUM(B2:Z2)

💡 Hint

Use INDEX with COUNTA to find the last filled column in the row.

Option B uses INDEX to find the last non-empty cell in row 2 and sums from B2 to that cell, adapting to changing columns.

How many cells are selected by this range?

In Google Sheets, what is the total number of cells selected by the range C3:E5?

A 9

B 6

C 12

D 15

💡 Hint

Count how many rows and columns are included in the range.

The range C3:E5 covers 3 columns (C, D, E) and 3 rows (3, 4, 5), so 3 x 3 = 9 cells.

Practice

1. In Google Sheets, how do you select an entire column quickly?

easy

A. Click the row number on the left

B. Click the column letter at the top

C. Double-click any cell in the column

D. Right-click a cell and choose 'Select column'

Solution

1. Step 1: Understand column headers

   Columns are labeled with letters at the top of the sheet.

2. Step 2: Select entire column

   Clicking the column letter selects the whole column instantly.

3. Final Answer:

   Click the column letter at the top -> Option B

4. Quick Check:

   Select column = Click column letter [OK]

Hint: Click column letter to select whole column fast [OK]

Common Mistakes:

• Clicking row number selects a row, not a column
• Double-clicking a cell edits it, doesn't select column
• Right-click menu doesn't have 'Select column' option

2. Which action correctly selects multiple adjacent cells in Google Sheets?

easy

A. Click one cell, then hold Ctrl and click others

B. Double-click a cell to select adjacent cells

C. Click the row number to select cells in that row

D. Click one cell, then drag across cells to select

Solution

1. Step 1: Understand selecting multiple cells

   Dragging the mouse across cells highlights all cells in the dragged area.

2. Step 2: Confirm correct method

   Holding Ctrl selects non-adjacent cells, not adjacent ones. Dragging selects adjacent cells.

3. Final Answer:

   Click one cell, then drag across cells to select -> Option D

4. Quick Check:

   Drag to select adjacent cells [OK]

Hint: Drag mouse across cells to select adjacent range [OK]

Common Mistakes:

• Using Ctrl selects non-adjacent cells, not adjacent
• Clicking row number selects entire row, not specific cells
• Double-clicking edits cell, does not select range

3. If you select cell B2 and drag the fill handle down to B5, which cells are selected?

medium

A. B2 to B5

B. B2 only

C. B1 to B5

D. A2 to B5

Solution

1. Step 1: Identify fill handle usage

   The fill handle is a small square at the bottom-right corner of a selected cell used to extend selection or copy formulas.

2. Step 2: Understand dragging down

   Dragging down from B2 to B5 selects cells B2, B3, B4, and B5 in the same column.

3. Final Answer:

   B2 to B5 -> Option A

4. Quick Check:

   Drag fill handle down = selects B2:B5 [OK]

Hint: Drag fill handle down to select cells below [OK]

Common Mistakes:

• Thinking only the original cell is selected
• Including cells above the start cell
• Selecting cells from different columns accidentally

4. You want to select row 4 but accidentally select row 5. How do you fix this quickly?

medium

A. Click row 4 number to select it

B. Drag from row 5 to row 4

C. Double-click row 4 number

D. Right-click row 5 and choose 'Select row 4'

Solution

1. Step 1: Identify how to select a row

   Clicking the row number on the left selects the entire row.

2. Step 2: Correct selection

   Click row 4 number to select row 4 and fix the mistake.

3. Final Answer:

   Click row 4 number to select it -> Option A

4. Quick Check:

   Select row = click row number [OK]

Hint: Click correct row number to select that row [OK]

Common Mistakes:

• Dragging rows does not select rows
• Double-clicking row number does not select row
• Right-click menu has no 'Select row' option

5. You want to select all cells in columns B and C and rows 2 to 4. Which method works best?

hard

A. Click column B letter, then hold Shift and click column C letter, then drag rows 2 to 4

B. Click row 2 number, then hold Ctrl and click row 4 number, then select columns B and C

C. Click cell B2, drag to C4 to select the range

D. Select row 2, then drag down to row 4, then select columns B and C

Solution

1. Step 1: Understand range selection

   Clicking and dragging from B2 to C4 selects all cells in columns B and C and rows 2 to 4 as a block.

2. Step 2: Compare other methods

   Click column B letter, then hold Shift and click column C letter, then drag rows 2 to 4 mixes column and row selection separately, which is less efficient. Options C and D do not select the exact block correctly.

3. Final Answer:

   Click cell B2, drag to C4 to select the range -> Option C

4. Quick Check:

   Drag from top-left to bottom-right cell to select block [OK]

Hint: Drag from top-left to bottom-right cell to select block [OK]

Common Mistakes:

• Trying to select rows and columns separately
• Using Ctrl instead of Shift for adjacent rows
• Selecting rows or columns without dragging cells
